Building Layout Generator
Building Layout Generator: From the Lot to the Top Floor
Some plans are bigger than a room: a two-story house with a basement, a café with a service counter, a shop with aisles, a building on its lot. RoomSketch3D handles all of it in one design — floors stacked with real stairs and elevators, commercial fixtures sized from spec sheets, and the yard, fences and driveway around it.

Floors that line up
Add a floor and the one below shows through as a guide, so walls stack where they should. Draw stairs between floors — straight, L, U or spiral — and an elevator that serves the floors you choose. Basements work the same way, and the 3D view stacks everything.
Every floor of your home
Cafés, shops and restaurants
Start from a commercial template — a café, a small restaurant, a fast-food counter, a grocery store, a laundromat, a library, a gym — and adapt it. Commercial equipment is sized from manufacturer spec sheets, and Smart Flow Check flags doors and doorways blocked by fixtures, just as it does at home.
Cafés, shops and food trucks
The lot around it
Wrap a yard around the building: lawn, driveway, walkways, planting beds, trees and fences along the real property line. Everything shows in 3D with the building, so you can see how the house sits on its lot.
Yard and outdoor design
Hand it on in CAD
When the layout goes to an architect or engineer, export a layered AutoCAD DXF at real scale — exterior and interior walls, doors, windows, stairs, elevators, furniture and fixtures, and dimensions on their own layers — or a print-sharp PDF up to A0.
How the DXF export works
What it does — and what it doesn't
It does
- Lays out several floors with stairs, basements and elevators
- Opens commercial templates with spec-sized equipment
- Places the building on a lot with yard, driveway and fences
- Exports a layered DXF, PDF up to A0, PNG or a 3D model
It doesn't
- Generate a building automatically from a brief — you draw or import the layout
- Check building codes, fire egress or occupancy loads
- Produce structural, MEP or permit drawings
See it in the full demo
The 3:25 demo builds a two-story home from a blank page. It starts at 1:10, “Add a second floor” — scrub back to watch the whole build.
Building Layout Generator questions
Straight answers, including the limits
Can I lay out a building with more than one floor?
Yes. Add floors and basements, connect them with stairs (straight, L, U or spiral) and add elevators that serve the floors you choose. The floor below shows through as a guide while you draw.
Does it work for commercial spaces?
Yes — there are templates for a café, restaurants, a fast-food counter, a grocery store, a laundromat, a library, a gym and more, with commercial equipment sized from manufacturer spec sheets.
Will it check my layout against building codes?
No. Smart Flow Check catches practical problems like blocked doors and doorways, but it doesn't check codes, fire exits or occupancy. Use the plan to work out the layout and have it reviewed by a professional.
Can an architect use my layout?
Yes — export a layered AutoCAD DXF at real scale, or a print-sharp PDF up to A0.
